A thorn to other durians’ pride

Pro at work: Teoh using a blade to sniff a durian’s flesh to determine its ripeness. At left, the Black Thorn durian.

GEORGE TOWN: It is almost symmetrically round like a ball and unlike other durians, it has a single blackish brown to dark brown thorn at the centre of its base.

The Black Thorn durian is at once one of the easiest durians to pick out and also one of the most expensive.
